I just got a Libre. I installed a few books I have that are ePub. Just to check it out. Some of them I can read. Others I can't read. The ones I can't read I installed through Adobe Digital. Still not readable, just cover picture and locks up. I then tried to read with Adobe Digital and had no problem. I still cannot read on Libre. I think most of my books have been converted from htm with Calbre.

Any suggestions?
